-white and
cinnamon-brown.

The hymenium is smooth, cream-white.

This species is found on decayed limbs and trunks of trees.

_Hymenochaete. Lev._

Hymenochaete is from two Greek words, _hymen_, a membrane; _chaete_, a
bristle.

In this genus the cap or pileus may be attached to the host by a central
stem, or at one side, but most frequently upon its back. The genus is
known by the velvety or bristly appearance of the fruiting surface, due
to smooth, projecting, thick-walled cells. I have found several species
but have only been sure of three.

_Hymenochaete rubiginosa. (Schr.) Lev._

Rubiginosa means full of rust, so called from the color of the plant.

The pileus is rigid, coriaceous, resupinate, effused, reflexed, the
lower margin generally adhering firmly, somewhat fasciated; velvety,
rubiginous or rusty in color, then becoming smooth and bright brown, the
intermediate stratum tawny-ferruginous. The hymenium ferruginous and
velvety. It is found here upon soft woods such as chestnut stumps and
willow.

_Hymenochaete Curtisii. Berk._

Curtisii is named in honor of Mr. Curtis.

The pileus is coriaceous, firm, resupinate, effused, reflexed, brown,
slightly sulcate; the hymenium velvety with brown bristles. This is
common on partially decayed oak branches in the woods.

_Hymenochaete corrugata. Berk._

Corrugata means bearing wrinkles or folds.

The pileus is coriaceous, effused, closely adnate, indeterminate,
cinnamon colored, cracked and corrugated when dry, which gives rise to
its name. The bristles are seen, under the microscope, to be joined.
Found in the woods on partially decayed branches.

CHAPTER X.

CLAVARIACEAE--CORAL FUNGI.

Hymenium not distinct from the hymenophore, covering entire outer
surface, somewhat fleshy, not coriaceous; vertical, simple or branched.
_Fries._

Most of the species grow on the ground or on well rotted logs. The
following genera are included here:

Sparassis--Fleshy, much branched, branches compressed, plate-like.
Clavaria--Fleshy, simple or branched, typically round.
Calocera--Gelatinous, then horn-like.
Typhula--Simple or club-shaped, rigid when dry, usually small.

_Sparassis. Fr._

Sparassis, to tear in pieces. The species are fleshy, branched with
plate-like branches, composed of two plates, fertile on both sides.

_Sparassis Herbstii. Pk._
